Dell Inspiron 15 - 3000 series - Beep Beep Beep Pause Beep Beep Beep

Hi,My laptop here is a Dell Inspiron 15, 3000 series. The laptop itself works perfectly fine, I am able to get into windows (which I installed myself, it originally came with Ubuntu). Occasionally though, it will do a BEEP BEEP BEEP PAUSE BEEP BEEP BEEP PAUSE (repeats).This happens on boot and sometimes when I am using it. Sometimes it turns off suddenly when I am shifting the computer around. It's extremely loud.

What is causing this? The sound seems to be coming from around the area the Memory banks are under the laptop, but nothing seems to suggest that anything is wrong.I took a suggestion and used FN+Power to do Hardware Diagnostics which said nothing is wrong.

Hi,I’d suggest that you follow the steps mentioned below and check if the beep pattern repeats.

Switch off the computer.Disconnect the AC adapter from the system.Remove the battery from the computer.Press and hold down the power button for 15 seconds.Then connect back all the peripherals and check if the beep pattern repeats and reply us with the beep count.

If you still receive 3 Beeps on the system then it indicates System board failure.. You will have to replace it on the laptop.Please let me know the findings.

Hi Ganny,What are the exact # of beeps in a cycle? Kindly review this chart and see page# 47 - it will help isolate the source of the issue. Based on the exact # of beeps, that part would need to be replaced.Also, please click my DELL-username and write me a private message with the service tag and your Name for case records.Let us know if you have any other queries.

My X230 gets very little use since I bought it in 2012... sometimes no use at all for weeks at a time. Yet the system board failed, as did a replacement, and now the third board seems to have failed. On startup I get 1 beep, 3 beep, 3 beep, 1 beep and a blank screen. I tried the existing RAM stick in both slots: no startI bought and tried a NEW stick of RAM from Crucial in both slots: no startI tried both sticks in the slots at the same time: no start Other than another bad system board, what could it be? Where can I get a system board that might last? By the way, at the same time I bought the X230 I also bought a T530 that gets gallons of heavy use almost every day and never had a problem that I didn't cause myself.

A few times now my E5440 will give a low beep... then a few seconds go by, and another beep. It just happened a minute ago - only two beeps this time. But I think it happened a few days ago and beeped several times with the same pause of a few/several seconds in between the beeps. It's so quiet that before I've thought I was imagining it. But this time I was sitting in front of it typing.There are no pop-up notifications on the screen anything is wrong, such as the 'disconnection' sound when you remove a portable HDD, or your Wi-Fi disconnects. Nothing to indicate what the beeps mean. The laptop is working perfectly. Battery is fully charged. I can hear the fan turning and changing speed but it's 2:30am here with no outside noise and I can barely hear the fan. (I assume it would be spinning up like crazy if something were overheating.)I'm at a loss what it means. Does anyone know?I'm running Windows 7 Pro 64-Bit if that matters.

I have two printers connected to a Dell E520 through Vista. They are a Brother 5440CN and a HP 6110xi. The .Brother works ok but I can't say the same for the HP. Clicking any button on the HP gives the same response. Beep, beep, beep. I have recently moved the system to a new location just a couple of feet from where it was. Before the move Brother would scan and copy and the HP would do the same, but now as noted I can't get any response out of it but beep, beep, beep

Anybody have any ideas??.

i shut it down properly upon finding that my C key was on the fritz. a couple of months ago, my E key had been doing the same (randomly not working and randomly typing e consistently). once i rebooted, i got the message "Operating System (OS) Not Found".

i let my computer rest for a while and turned it back on. i currently get the toshiba startup, but around when it's suppose to load the os, it beeps continuously at the loudest volume with a contantly blinking underscore in white font on a black background.

i believe this may have happened once before, but i have no clue what i did to fix it.

hello everyone,i had this problem last night i tried to uninstall program that i suspect as a virus and after that i wasnt able to turn on my computer, i heard 3 beeps, on the first place im able to go to safe mode by pressing the f8 but now im stuck with the 3 beeps constantly repeating the same thing, I dont know what to do , I need to do my homework pls help me. thank you

Hello, Welcome to BleepingComputer.I'm nasdaq and will be helping you.If you can please print this topic it will make it easier for you to follow the instructions and complete all of the necessary steps in the order listed.===The 3 Beeps are most likely coming from the BIOS and is an indication that your have some Hardware problem.Could be RAM or a failing Motherboard.Check it out.http://www.computerhope.com/beep.htmBringing you computer to a qualified technician is probably your best option.

Hi,my old BIOS IVKT06AUS I flash to new BIOS IVKT07A If i connect power adapter my computer automaticaly start without push the power button but start OK to Win.If i go to sleep mode and wake up with keyboard computer start to black screen and speaker starts beep 3x short beep 1x long beep :-(If i long push power button computer is off and i again short push power button computer start correctly (i see all running aplication as i wake up from sleep).From windows i switch off computer. Now if i disconnect power adapter and connect again i hear only beep and black screen (black screen and speaker starts beep 3x short beep 1x long beep)Again i must long press power and short press power and computer again working.I try change memory but same problem :-( Previous BIOS is OK withou this symptoms. I think is problem in new BIOS :-( Sorry for my English :-)Please help me.Thank You.

Here is my problem I have a Compaq presario with a frozen bios screen but cpu ok, mem ok, video ok, nothing is conected and power supply ok.any ideas?

A:Compaq bios freeze short beep long beep

Is the beep pattern just one short one long? Check your manual for the POST beep codes to determine what it is telling you. All POST beep codes are different so there's no way to tell unless we know exact model of your PC. The manual usually has the beep code in it, though.

My tower is not booting up when I turn it on. My son took the side off and was going to put more memory in it for me, but in the end he didn't. He put the old memory back in and put the side casing back on. Today, when I turn it on, it has 1 short beep and 1 long beep. It just won't boot up. Can anyone tell me what I need to do to get it back up and running?

RBurke, welcome to the forum. The BIOS Beep Code that you are hearing is caused by a memory problem. Here is a guide that will help solve the problem: http://support.hp.com/us-en/document/bph07107 You should read the entire page.

For some silly reason I removed the 2 128mg PC2100DR ram sticks from my old computer that was working just fine. When I reinstalled them and I try to boot up I get a long beep, a pause, and another long beep. This senario continues and I shut the computer down as soon as possible. I'm sure I have the ram seated properly. Any ideas? Thank you in advance

A:One long beep, pause, another long beep when I turn on computer

If you are sure that you have them seated correctly try one stick at a time.

I am trying to help with a Dell Inspiron 5100.The computer was running very slow and I've made a bit of progress resolving that. I think it needs some more RAM and I'm not sure if that could be at all related to the following.The problem now is that after running for few hours, then shutting down, then trying to turn back on:1. light comes on indicating computer is on2. the computer makes 2 beeps3. wait...black screen4. wait...black screen5. and so on

This does not happen everytime trying to start the computer so I'm really at a loss. I've read about overheating in this model which would seem to make sense but sometimes this will happen after the computer has been off for a day or so.

My computer has been making this noise for quite some time now. but it would only happen once every few days so it didn't really concern me until now because its happening non stop. The noise is definitely coming from system sounds. I'm not sure if this is related but under device manager there is an unknown device which i cannot account for as i put the computer together and I'm staring in to the case rite now. there is also a yellow icon by teredo tunneling pseudo-interface (i have no idea what that is)lately my computer just seems to be working really hard when idling. the cpu is constantly spiking up to 100% usage and my hard drives seem to constantly be spinning. specscpu: intel core 2 duomobo: abit ab9ram: 1gb ddr2gfx: geforce 9800 gtx+hd: 2 seagate internal drives (1 with os) the other blank for storage. In my mind there are two possibilities. 1 i have some sort of virus. 2 some hardware is malfunctioning. either way i have no idea where to start and i was hoping someone could point me in the rite direction. Thank You!

A:Weird beep beep boop noise

You should check for malware first. I'll ask a mod to move this to the appropriate forum.

most of the time I start my computer I get five beeps pause of few seconds and then 2 beeps. Initially, it was five beeps on;y but the last two have been started recently. what is it about? how can I solve this problem?

A:5 beep pause 2 beep

The beep sequence refers to the CMOS battery - or the clock chip. Replace the reserve (CMOS) battery -- it's usually a CR-2032 button cell. If you need details, post the model number (i.e., Inspiron N5110, XPS 9333, etc.).

Hi there i seriously need you guy's help with my model # P6310Y.I continually hear 1 short beep and 1 long beep when i try to boot up my pc.According to hp it's a memory issue but i proved that wrong.I have gone thru removing the RAM checking if one of the modules are bad.they are all good 2gb x 3.I also removed the windows 7 harddrive and i still get the beeps i described above.I made sure all cables are seated properly and i cleaned the entire MOBO for dust including the CPU.I get a blank on my monitor nothing shown.When i plug in the keyboard i don't get any power, lights etc(num lock,caps lock)The mouse is getting power.I replaced the power supply still getting the beeps and i can remove all cables,hd,mouse,KB and the beeps continue.Please help me guys as i have hit a dead end and i appreciate your time,Sincerely, tech1126

I tried to start the computer but I am just getting one short beep followed by a long beep. I think it has to do with the ram. I tried reseating the ram in different combintations but none of them seem to improve the computer. edit: oops I put this in the wrong section. I have a desktop not a notebook sorry for the confusion

I was just using my PC yesterday, everything is normal, It was hot around 32 ?C I think. Around 3:00 P.M. my PC suffered 2 BSODS, I can't upload the .dmp files because I can't open it. I thought its just overheating so I turned it off and after a few minutes the second BSOD appeared, I restarted my PC and the one short beep and one long beep is sounding. I checked my RAM and tried to switch it to another bank but the beeping is still there. My video card temp was 50-52 ?C before the first BSOD happened. What can I do to fix this?

A:One short beep, one long beep

Is it possible you are hearing 1 long - one short?That might indicate a BIOS CHECKSUM error, depending on the brand of BIOS.

You can try a ClearCMOS procedure (CLRTC is the same thing): Note all your current BIOS settingsShut down the computer > remove the power cord.Remove the 3v motherboard battery.Move the CLRTC jumper from pins 1-2 to 2-3.Touch a metal part of the case and Press and Hold the reset button for approx. 30 seconds to discharge all power from the board.Put the CLRTC jumper back on pins 1-2.Replace the 3v battery > replace the power cord > boot.Immediately go back into BIOS and reset all your preferred settings. If the CLRTC worked you will need to reset the date and time.

Hopefully this is the right forum for this. I got an HP Pavilion Elite HPE-180t CTO Desktop PC. I know it is an old machine but it has been working okay up till the other day. I was having some memory issues so I reseated all my ram. Now it will not start but does one short beep then one long beep. I figured it was a ram issue but I do not know how to solve the issue.

Hi, Today I replaced my old graphics card with a new GeForce 9500GT and also added a new Kingston 2GB Ram Card. I installed both of them then restarted the computer, since then it has only powered on and playing 1 short beep then 1 long beep. I've tryed everything I can think of ranging from taking out everything new and putting it back to before I added the new items to completely taking out all 3 RAM sticks and reseating them. I'm not sure how a brand new unopened 2GB ram stick that fit perfectly and a brand new right out of the box graphics card can cause a problem like this. I've been through the ins and outs of the internet trying to find a solution but nothing has worked. Hoping someone can think of a unique way to fix this or how it could have possibly happened in the first place. I dont buy anything used everything placed inside my computer was/is brand new when it was purchased. Any help/comments on solutions would be greatly appreciated thanks.

hello, i have a hp a335w i just installed a new power box 2 days ago pc was working fine ,but today when i turned pc on i got one short beep then one long continues beep i disconnected the memory , harddrive, cd, one at a time to check for problem but still have the same problem pc will not boot up

Hi, I have a acer travelmate 4070 laptop when you turn it on it starts beeping loud,I started clicking enter so it can boot quick lol as soon laptop booted, opened windowwent to normal screen operation it stopped beeping.I gave it a shut down, turned it on again and that loud beeping started again.Sounds like a smoke detector lol the beep wont stop, what can it be ?

A:Beep, Beep wont stop

how many beeps? tell us the sequence of beeps heard. need more specs of your machine as well

I just had a "search engine redirect issue" fixed by "Gringo." One thing that is different now is at windows start-up, this laptop makes a BEEP TIC (Higher in frequency than the BEEP) vs the BEEP BEEP sounds I've had for ever. The computer start-up sequence is very slow as it takes minutes before the computer is ready to be used.

During the virus removal, a few times the reboot start-up sounds were BEEP - TIC - BEEP (again the TIC was higher a higher tone and faster than the BEEPs). What do the different sounds mean?

I turned my wife's computer on and the screen didn't even flicker and all it does is beep at me.I tried removing on componant at a time and started it after every removal.Still beeps at me.Until I got to the CPU. It stopped beeping at me. Of course, every other piece was out of the puter, so I'm not sure if its supposed to stop beeping or if thats the problem.Any ideas?

As the title says my PC outputs a "beep beep" sound out external speakers. It is extremely annoying. I haven't the slightest clue why it does this. Its kindof i higher pitch beep beep. all my specs are on my profile.

I just got new asus AM2 mobo and I'm getting beeps on start. 1 long beep and two short. Somewhere I found it is related to video card. I'm not sure if that's true, but I know videocard is functional and inserted correctly.
The mobo has it's own video, so I tried using only that, same thing. It just doesn't seem to make sense.

A:Beeeep, beep beep

One long two short looks like a video issue, as you said. You say it is also happening when you remove the graphics card and try to boot up with the onboard graphics?

Here's what I'd do:

Remove the motherboard from the case and set it on a box beside your case. Next, reset cmos (check your manual to find the cmos jumper pins).

Remove everything from the motherboard except:

cpu with heatsink/fanone stick of rampower supply connections to the motherboard (should be two)connect the case's speaker to the motherboard

Then use a screwdriver to quickly touch (short) the two pins that usually connect to your case's power on switch.

See what kind of beeps you get.

If you still get the beeps, my guess is your need to RMA the board, but please post your system's full specs (including your power supply specs)

I just got a strange reaction from my pc. It was working fine last night, I went to start, turn off computer, shut down and went to bed. I got up this morning and I saw a notice on the screen (PC did not shut down during the night) It said there was a change to the global template for microsoft word and did I want to save changes so I said no and the pc shut down. Later on I tried to call up my key logger and heard a beeping noise from within my pc. I paid it no attention and went on the rest of the day working. I was using Quicken later on and noticed that when I tried to view certain graphs they seemed to be "fluttering" (The page seemed to go up and down rapidly on its own) I closed it and ran Avast antivirus scan. I tried to activate it and got an error message that said it ran into some kind of runtime error (I think) I finly got it started, ran a scan and came up empty of viruses. Then Avast kept shutting itself off. I emptied my waste basket, went to internet options, deleted all files and history (Including online content) then cleared all in Firefox. Next I went to start, run msconfig, start up disable all, restart, back to start, run, msconfig, enable all, reboot and everything seems to be fine now. Can anyone tell me what this may have or still is?

Hi there,We have recently purchased (last month) a Latitude E5570 with docking station. We experience system hangs and freezes several seconds, sometimes up to a minute after hot undocking the laptop. The mouse and keyboard become unresponsive.

It usually emits a beep code before freezing up. 4 beeps then a pause and then 1 beep. Any information regarding this?Anyone have insights into this?Thanks!

Hi! I have been using dell inspiron for almost 2 years. Everything was working fine all through till now. Two days back I turned it on as usual but it didn't start. The power button lights up , I hear the fan , the dvd drive works , but the screen doesn't start and after some time I get 3 beep sounds consecutively with gaps in between. I left it aside and turned it on again after 24 hrs and it started normally and worked as usual. Then I turned it off and switched it on again after 1 hour but it didn't start and again I get the beep sounds. It remains so till now. What should I do ? ?

A:Dell inspiron 3 beep sounds

Unplug the system, remove or disconnect the battery, and hold the power button for 30 seconds. Remove and reinstall the memory module(s).Try powering up - if that clears it, you're set. If not, budget a few hundred dollars for a replacement mainboard -- or depending on the model, for a new system (sub-$700 systems aren't really worth a major repair like a mainboard once they're out of warranty, as the cost will exceed 50% of that of a new system).

I'm getting a single beep at seemingly random intervals on my Dell Inspiron 1545, Windows 7 64 bit. The beep comes from inside the laptop, it doesn't come through the main speaker (from the motherboard I assume).

I've searched and have found the beep codes and according to that it is "BIOS checksum failure. Possible motherboard failure". I have no idea what a BIOS checksum failure means though. I have been told that this isn't a beep code though as it doesn't happen at boot. It can happen every few minutes or several days can pass without hearing it.

I don't seem to have any problems at all, everything runs as it should. I think the beeping might have started when I replaced my hard drive, although I'm not 100% sure about that. I can't really contact Dell as the warranty has run out.

My battery is also pretty much dead and while I don't need it at all, I wonder if this may have something to do with it?

I have disabled the beep entry in the registry but that hasn't solved the problem. I have also flashed the bios with the latest one but this also didn't help.

Hi, if someone could help me would be great! I receive this 7beep code from the motherboard every time I try to boot my inspiron duo 1090, nothing on screen just a 7 beep code not like 3-2-2 or 3-4 or something is a 1-1-1-1-1-1-1. I saw around the net that this is common and is just a fake alarm from the motherboard, and that dell support have told ppl to just press the FN key while booting and that bypasses the P.O.S.T. and boots like nothing again, some ppl say the just left they're computer there and tried like 2 weeks later and booted like normal. I tried this FN key to bypass the P.O.S.T. but NOTHING happened and my duo is out of warranty already and I don't wanna pay for a fake code or something please somebody help me =(

A:Dell inspiron duo 7 beep code at start up!!!

I found an American webpage telling how to solve this within half an hour. At first I thought is was mad. I was desperate so I tried it.With the laptop on and beeping away wrap it up tightly in a large towel and place under the duvet. Leave it for 1/2 hour and then unwrap and switch off. Leave it to cool down and then switch on. I writing this on a dell laptop that had the 7 beeps and the above treatment.It works!!!

Hi, I own a Dell Inspiron N5110 i5 processor laptop with 4 GB RAM and 500 GB hard disk. Its getting 14 months since I bought it.From the last few days, I could see that the machine makes beep sound on start up till the windows starts. The sound gets disappeared after OS starts. Especially if I turn on the lap from hibernation mode, some time rebooting also make the beep sound. However, I observed a similar low tone inside the system even when the machine is running. I have been using a cooler also to reduce the heat, all keys are working fine no thing is jammed, I have performed the dell H/W diagnostics test all the results were passed. Drivers are all updated, the processor fan i also running correctly. I am wondering what can be the reason.
Please do share your thoughts and suggestions about this issue.

I have tried something from another forum that I found, but do not have the link so I cannot copy and paste or give credit to the poster. This is what I did:1) Unplug all power from the laptop2) Remove the battery3) Hold down the power button for approximately 15 seconds.4) Reattach the battery and/or plug in the power supply.5) Power on the laptop.This solved my problem.

Hello,I have a Dell Inspiron 3521 Laptop.Firstly, I have detected a problem with the display, some pixels on the monitor were not loaded successfully. The number of those pixels has significantly increased over the time and, further, the laptop has begun to start at a second try, the first try involving a beep at power on, thus avoiding the initialization of the system.At the moment, when trying to power on the laptop, it starts with a single beep which suggests me that it is a "Motherboard: BIOS ROM Failure" fault.However, I don't know how I could proceed in detecting the problem(s) and getting the laptop firstly to boot correctly and secondly to avoid the failure of loading the pixels. Furthermore, do you think that those problems are somehow related?Thank you in advance.Best regards,Roxana Stan

Unplug the system, remove the battery (or unplug it if it's internal) and hold the power button for 30 sec. Remove the base cover and both memory modules and reinstall them.If that clears the single beep issue, hold the D key through powerup, which will start an LCD built in self test. If the screen then shows solid colors OK, it's fine.If it does not - or the single-beep issue isn't cleared -- the first step is a big one: the mainboard needs to be replaced. You're looking at about $300 or more with labor - and on a low-end system like this one, you may find it better to replace rather than repair a major fault such as a bad mainboard.

got a a desketop, just buought a gtx 480 for it.. great.... my pus didnt have the 6 or 8 pins connectors, so i used another psu i have.... BAD idea... didnt boot but insted gave me BEEEP BEEEP BEEEP BEEEP.....no power. also sounded like a spark or something kinda "crikiling." great so i put my stock psu back and my weaker 6770 and.... .... no power.... no boot.. no beeping...

Hi,My Dell Inspiron N4050 laptop (4 yrs old) continuously beeps on startup and it goes when I press any key. But it is getting hang as soon as the windows is open and getting an error message like windows performance is low. Please let me know the reason for this issue and how it can be fixed.Thanks Nidheesh

My PC gives a very long beep when it starts up. But it does start up. More over, it automaticall types the / character in the password field sometimes.sometimes behaves upnormally by not letting to type any character....Y is it so?

Try running the Dell Diagnostics Test (the full version) to see if it detects any problems. Here's how: How to Run the Dell. If it does, contact Dell Support for assistance (there's a link near the bottom of the above article).

I hope this helps. If the test comes back completely clean, then post back and we'll try something else (or if your computer is still under warranty, contact Dell Support anyway as they should be happy to assist you and know more about your computer than we do).

So I log out the evening before on my HP Presario SR1010 and when I try to restart on the next AM.... nothing! No screen or message, no signal output, just a long, continuos, intermittent beep of about 2-3 seconds. A situation that has never occured before. After removing each peripheral individually and restarting after each removal, nothing changes. I opened up the chasis and cleaned it thoroughly, removed the boards, cleaned and replaced them, nothing changed. I've checked for a beep code but haven't found a similar description. Any thoughts or suggestions ?

A:HP Presario shut down with long beep series

http://www.fixya.com/support/r1569455-beep_code_explainedhas a relatively long list of beep codes. Your PC uses Award BIOS. I didn't totally understand your description of the beep, but from what I could tell it seems to be a memory problem, though I may be off on that.

I take it you did reseat the memory? If not you should try that, if that doesn't fix it you'll want to remove the memory sticks one module at a time to see if the board eventually stops beeping on you. If it does, you can diagnose which stick is bad and should be replaced.

The other problem that may fit your beep is a bad power supply. That's difficult to test unless you have another, either in a second computer or just extra. Check to make sure it is powerful enough to run your machine!

My notebook is making 8 beeps in loop, i've tried the lcd screen test with letter D and seems to work fine all colors are correctly displayed, i have changed memory, Hard Disk, disconnected battery, disconnected lcd cable, problem still remains, is it possible at this point that main board is gone?
